Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, specifically a leak-proof integrated nozzle and floor scrubber. Background Technology

[0002] With the development of technology, automated equipment has gradually become widespread in all walks of life. In the cleaning industry, the cleaning of floors has gradually shifted from manual sweeping to cleaning using cleaning equipment. In places with large hard surfaces such as stations, docks, and airports, manual sweeping is very inefficient. Therefore, floor scrubbers have been introduced to replace manual sweeping.

[0003] When the floor scrubber is working, the motor drives the main brush and brush disc to rotate through gear or belt transmission. With the help of clean water or detergent, the brush rotates and rubs against the ground to achieve the cleaning effect. Then, a vacuum motor generates a high-speed airflow to create a vacuum inside the wastewater tank. The rubber strip then contacts the floor squeegee, which collects the wastewater and draws it into the wastewater pool through the high-speed airflow, thus achieving a rapid cleaning of the site.

[0004] However, when the floor scrubber stops and the integrated nozzle is raised to an angle or placed vertically, air will enter the interior of the integrated nozzle body from the nozzle at the higher end. The water inside the integrated nozzle will flow down the flow channel, causing the water inside the integrated nozzle to flow out from the nozzle at the lower end, resulting in side leakage after the floor scrubber stops.

[0005] Therefore, the present invention provides an integrated nozzle for preventing side leakage and a floor scrubber. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: An integrated anti-leakage nozzle of the present invention includes a spray base; a flow channel is fixedly connected to the inner cavity of the spray base; multiple water outlet holes are evenly distributed on the bottom surface of the inner cavity of the spray base; the water outlet holes are evenly distributed inside the flow channel; multiple cavities are evenly distributed at the bottom of the spray base; the cavities and water outlet holes are alternately distributed; a connecting groove is formed in the middle of each water outlet hole; adjacent cavities are connected through the connecting groove; an elastic tube is provided inside each water outlet hole; the elastic tube passes through the connecting groove; guide rods are fixedly connected to both sides of each of the multiple cavities; the guide rods pass through the outer wall of the cavity; the inner cavity... The unit is equipped with a counterweight seat; sliding sleeves are fixed to both sides of the counterweight seat; the sliding sleeves are fitted onto the outer ring of the guide rod; push blades are provided on both sides of the counterweight seat near the connecting groove; the push blades are slidably engaged with the connecting groove; when the water spray seat is tilted, the counterweight seat, under the action of gravity, drives the sliding sleeves to slide along the guide rod towards the lower end of the water spray seat, causing the push blades at the lower end of the counterweight seat to slide into the interior of the connecting groove. The push blades push the middle part of the elastic tube, causing the middle part of the elastic tube to bend and compress, squeezing and sticking the outer walls on both sides of the elastic tube together, blocking the elastic tube, thereby preventing the water remaining inside the flow channel from flowing out from the lower water outlet, thus improving the dryness of the ground around the floor scrubber.

[0008] Preferably, springs are fixed to both sides of the sliding sleeve, and the springs are sleeved on the guide rod; a linear bearing is provided in the inner ring of the sliding sleeve; the spring force makes the water spray seat horizontal, and the counterweight seat and push shovel are reset, ensuring the unobstructed flow of the elastic tube.

[0009] Preferably, the top surface of the counterweight seat has an installation groove; a square magnet is bolted inside the installation groove; adjacent square magnets repel each other; U-shaped brackets are fixed to both sides of the counterweight seat near the connecting groove; the pusher is fixed to the U-shaped bracket by locking bolts; through the mutually repelling square magnets, when the counterweight seat slides to one side, the repulsive force between the square magnets will push the lower counterweight seat to move, thereby making multiple counterweight seats move synchronously, thus improving the efficiency of multiple elastic tube closure.

[0010] Preferably, both the top and bottom ends of the elastic tube are fixedly connected to a convex ring; the convex ring slides in fit with the outer wall of the water outlet; an elastic diaphragm is fixedly connected to the inner ring of the top convex ring; and a hole is opened in the center of the elastic diaphragm; in the initial state, the hole of the elastic diaphragm is in a sealed state, but after the floor scrubber is turned off, the water pressure inside the channel is low and cannot open the hole of the elastic diaphragm, thereby preventing the probability of water leakage inside the channel after the floor scrubber is turned off.

[0011] Preferably, a pair of guide rails are fixedly connected to both ends of the spray base; a slider is slidably installed inside the guide rail; an L-shaped clamp is fixedly connected to the side of the two sliders that are close to each other; a U-shaped magnet is installed between the two L-shaped clamps; the two ends of the U-shaped magnet are close to the spray base, and the U-shaped magnet is locked to the L-shaped clamps on both sides by bolts; a lead screw is rotatably installed inside the bottom guide rail; a waterproof motor is fixedly connected to one end of the bottom guide rail; the shaft of the waterproof motor is fixedly connected to the end of the lead screw; when the floor scrubber cleans the inclined ground, one end of the U-shaped magnet repels the adjacent square magnet, pushing the lower counterweight seat to slide back to its original position, causing the pusher to separate from the elastic tube, ensuring the unobstructed flow of the elastic tube and ensuring the working stability of the floor scrubber.

[0012] Preferably, a water filter seat is fixedly connected to the top of the water spray seat; a through hole is opened in the middle of the water filter seat; the through hole connects to the middle of the flow channel; a threaded interface is fixedly connected to one end of the top cover of the water filter seat, and the threaded interface connects to the interior of the water filter seat; this reduces the probability of small impurities in the clean water causing blockage in the flow channel and the elastic tube.

[0013] Preferably, a U-shaped plate is fixedly connected inside the water filter base; the opening of the U-shaped plate is away from the threaded interface; the through hole is located in the middle of the U-shaped plate; square rod-shaped mesh frames are slidably installed on both sides of the end of the water filter base away from the threaded interface; through grooves are opened on all four sides of the outer ring of the mesh frame near the opening of the U-shaped plate; a connecting plate is fixedly connected between the two mesh frames; the connecting plate is fixed to the water filter base by bolts, and the connecting plate and the water filter base are sealed by a sealing ring; multiple bamboo charcoal filter elements are evenly arranged inside the mesh frame.

[0014] Preferably, the bamboo charcoal filter element is square, and the bamboo charcoal filter element slides in fit with the inner wall of the mesh frame; the bamboo charcoal filter element has multiple holes evenly opened along the axial direction of the mesh frame, and multiple straight grooves evenly opened on the side of the bamboo charcoal filter element; the holes and straight grooves on the bamboo charcoal filter element are arranged perpendicularly; the clean water fully contacts the bamboo charcoal filter element during the flow process, so that the bamboo charcoal filter element fully adsorbs the impurities in the clean water, thereby effectively improving the cleanliness of the clean water.

[0015] Preferably, multiple partitions are uniformly fixed to the side of the bamboo charcoal filter element near the through groove; an elastic mesh plug is slidably installed on the inner ring of the opening of the mesh frame; the partitions separate adjacent bamboo charcoal filter elements, reducing the probability of bamboo charcoal filter elements sticking together, and improving the flowability of clean water; the elastic mesh plug fixes the bamboo charcoal filter element inside the mesh frame, reducing the probability of the bamboo charcoal filter element detaching from the inside of the mesh frame.

[0016] Preferably, a hinge is fixedly connected to the middle of the top cover of the water filter base; an angle sensor is fixedly connected to the end of the top cover of the water filter base away from the threaded interface; a hydraulic rod is hinged between the top side of the hinge and the top cover of the water filter base; this provides a basis for opening and sealing the water spray base; at the same time, adjusting the angle of the water spray base with the hydraulic rod not only reduces the probability of side leakage of the water spray base, but also facilitates the adjustment of the water outlet angle of the water spray base.

[0017] Preferably, the flow channel is divided into four cavities, and the four cavities are arranged in pairs; the two groups of cavities are symmetrically distributed along the middle of the water spray seat to both ends; the water outlets are set at both ends of each cavity; the water outlets are evenly distributed through the flow channel, and at the same time, multiple water outlets are connected in parallel inside the flow channel, so that the water outlet gap is minimized and the uniformity of water output from the water spray seat is improved.

[0018] A floor scrubber employs the aforementioned anti-leakage integrated nozzle. The floor scrubber includes a body; a brush disc is provided on the bottom surface of the body; the anti-leakage integrated nozzle is disposed on the brush disc and provides clean water to the brush disc; a squeegee is provided on the bottom surface of the rear of the body; the anti-leakage integrated nozzle effectively blocks the probability of water leakage.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention discloses an integrated anti-leakage nozzle and floor scrubber, which comprises a spray base, a flow channel, an elastic tube, a guide rod, a counterweight, a sliding sleeve, and a pusher. When the spray base is tilted, the counterweight, under the action of gravity, drives the sliding sleeve to slide along the guide rod towards the lower end of the spray base, causing the pusher at the lower end of the counterweight to slide into the connecting groove. The pusher pushes the middle part of the elastic tube, causing the middle part of the elastic tube to bend and compress, squeezing and sticking the outer walls on both sides of the elastic tube together, blocking the elastic tube, thereby preventing the water remaining inside the flow channel from flowing out from the lower water outlet, thus improving the dryness of the floor around the floor scrubber.

[0021] 2. The anti-leakage integrated nozzle and floor scrubber of the present invention comprises a square magnet, a guide rail, an L-shaped clamp, a U-shaped magnet, a slider, a lead screw, and a waterproof motor. When the floor scrubber cleans an inclined floor, the waterproof motor located at the lower end of the spray base starts, driving the lead screw to rotate and driving the slider at the bottom to slide along the guide rail at the bottom. The U-shaped magnet is clamped and fixed by two L-shaped clamps, driving the U-shaped magnet to translate so that one end of the U-shaped magnet aligns with the adjacent square magnet, and the other end of the U-shaped magnet repels the adjacent square magnet, pushing the lower end counterweight seat to slide back to its original position, causing the pusher to separate from the elastic tube, ensuring the unobstructed flow of the elastic tube and ensuring the working stability of the floor scrubber.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1

[0038] like Figures 1 to 6 As shown in the embodiment of the present invention, an integrated anti-leakage nozzle includes a spray base 1; a flow channel 2 is fixedly connected to the inner cavity of the spray base 1; a plurality of water outlet holes 3 are evenly distributed on the bottom surface of the inner cavity of the spray base 1; the water outlet holes 3 are evenly distributed inside the flow channel 2; a plurality of cavities 4 are evenly distributed at the bottom of the spray base 1; the cavities 4 and the water outlet holes 3 are alternately distributed; a connecting groove 5 is provided in the middle of the water outlet hole 3; adjacent cavities 4 are connected through the connecting groove 5; an elastic tube 6 is provided inside the water outlet hole 3; the elastic tube 6 passes through the connecting groove 5; guide rods 7 are fixedly connected to both sides of the plurality of cavities 4; the guide rods 7 pass through the outer wall of the cavity 4; a counterweight seat 8 is provided inside the cavity 4; sliding sleeves 9 are fixedly connected to both sides of the counterweight seat 8; the sliding sleeves 9 are fitted with The counterweight 8 is located on the outer ring of the guide rod 7; push shovels 10 are provided on both sides of the counterweight 8 near the connecting groove 5; the push shovels 10 are slidably engaged with the connecting groove 5; when the spray seat 1 is in a horizontal state, the water flow is evenly distributed along the flow channel 2 to the water outlet 3, and then sprayed out from the water outlet 3; when the spray seat 1 is tilted, the counterweight 8, under the action of gravity, drives the sliding sleeve 9 to slide along the guide rod 7 towards the lower end of the spray seat 1, and drives the push shovels 10 at the lower end of the counterweight 8 to slide into the interior of the connecting groove 5. The push shovels 10 push the middle part of the elastic tube 6, causing the middle part of the elastic tube 6 to bend and compress, squeezing and sticking the outer walls on both sides of the elastic tube 6 together, blocking the elastic tube 6, thereby preventing the water remaining in the flow channel 2 from flowing out from the lower water outlet 3, thereby improving the dryness of the ground around the floor scrubber.

[0039] like Figures 4 to 6 As shown, springs 11 are fixed to both sides of the sliding sleeve 9, and the springs 11 are sleeved on the guide rod 7; the inner ring of the sliding sleeve 9 is provided with a linear bearing; during operation, when the water spray seat 1 is in a horizontal state, the elastic force of the springs 11 on both sides pushes the sliding sleeve 9 to slide along the guide rod 7 to the middle of the cavity 4, so that the counterweight seat 8 and the pusher 10 are located in the middle of the cavity 4, so that the pusher 10 is separated from the elastic tube 6; through the elastic force of the springs 11, after the water spray seat 1 is horizontal, the counterweight seat 8 and the pusher 10 are reset, ensuring the unobstructed flow of the elastic tube 6.

[0040] like Figures 5 to 6As shown, the top surface of the counterweight seat 8 is provided with an installation groove 12; a square magnet 13 is bolted inside the installation groove 12; adjacent square magnets 13 repel each other; U-shaped brackets 14 are fixedly connected to both sides of the counterweight seat 8 near the connecting groove 5; the pusher 10 is fixed to the U-shaped bracket 14 by locking bolts; in this embodiment, except for the square magnets 13, other components are not magnetic; the pusher 10 is installed on the U-shaped bracket 14 by bolts, and only one pusher 10 needs to be installed on the two counterweight seats 8 at both ends, which facilitates the installation and disassembly work of the workers; through the mutually repelling square magnets 13, when the counterweight seat 8 slides to one side, the repulsive force between the square magnets 13 will push the lower counterweight seat 8 to move, thereby making multiple counterweight seats 8 move synchronously, thereby improving the sealing efficiency of multiple elastic tubes 6.

[0041] like Figures 5 to 6 As shown, both the top and bottom ends of the elastic tube 6 are fixedly connected to a convex ring 15; the convex ring 15 slides in contact with the outer wall of the water outlet 3; an elastic diaphragm 16 is fixedly connected to the inner ring of the top convex ring 15; and a hole is opened in the center of the elastic diaphragm 16; the elastic tube 6 is fixed inside the water outlet 3 by the convex ring 15; initially, the hole of the elastic diaphragm 16 is sealed, but after the floor scrubber is turned off, the water pressure inside the flow channel 2 is low and cannot open the hole of the elastic diaphragm 16, thus blocking the water from flowing out of the flow channel 2; when the floor scrubber is turned on, the water pressure inside the flow channel 2 increases and opens the hole of the elastic diaphragm 16; thus preventing the probability of water leakage inside the flow channel 2 after the floor scrubber is turned off.

[0042] like Figure 4 and Figure 7As shown, a pair of guide rails 17 are fixedly connected to both ends of the spray base 1; sliders 18 are slidably installed inside the guide rails 17; L-shaped clamps 19 are fixedly connected to the adjacent sides of the two sliders 18; a U-shaped magnet 20 is installed between the two L-shaped clamps 19; the two ends of the U-shaped magnet 20 are close to the spray base 1, and the U-shaped magnet 20 is locked to the L-shaped clamps 19 on both sides by bolts; a lead screw 21 is rotatably installed inside the bottom guide rail 17; a waterproof motor 22 is fixedly connected to one end of the bottom guide rail 17; the rotating shaft of the waterproof motor 22 is fixedly connected to the end of the lead screw 21; during operation, the floor scrubber cleans the sloping ground. At this time, the spray base 1 is in an inclined state and water needs to be discharged from the spray base 1. At this time, the waterproof motor 22 located at the lower end of the spray base 1 starts, drives the lead screw 21 to rotate, drives the bottom slider 18 to slide along the bottom guide rail 17, clamps and fixes the U-shaped magnet 20 through two L-shaped clamps 19, drives the U-shaped magnet 20 to translate, so that one end of the U-shaped magnet 20 aligns with the adjacent square magnet 13, and one end of the U-shaped magnet 20 repels the adjacent square magnet 13, pushing the lower end counterweight 8 to slide back to its original position, driving the pusher 10 to separate from the elastic tube 6, ensuring the unobstructed flow of the elastic tube 6, and ensuring the working stability of the floor scrubber.

[0043] like Figure 1 , Figure 8 and Figure 9 As shown, a water filter seat 23 is fixedly connected to the top of the spray seat 1; a through hole 24 is opened in the middle of the water filter seat 23; the through hole 24 connects to the middle of the flow channel 2; a threaded interface 25 is fixedly connected to one end of the top cover of the water filter seat 23, and the threaded interface 25 connects to the inside of the water filter seat 23; during operation, the water tank of the floor scrubber is connected to the threaded interface 25 through a pipe, and clean water is introduced into the inside of the water filter seat 23, filtered by the water filter seat 23, and then enters the inside of the spray seat 1 through the through hole 24, which reduces the probability of small impurities in the clean water causing blockage in the flow channel 2 and the elastic tube 6.

[0044] like Figures 8 to 11As shown, a U-shaped plate 26 is fixedly connected inside the filter base 23; the opening of the U-shaped plate 26 is away from the threaded interface 25; the through hole 24 is located in the middle of the U-shaped plate 26; square rod-shaped mesh frames 27 are slidably installed on both sides of the end of the filter base 23 away from the threaded interface 25; through grooves 28 are opened on all four sides of the outer ring of the mesh frame 27 near the opening of the U-shaped plate 26; a connecting plate 29 is fixedly connected between the two mesh frames 27; the connecting plate 29 is fixedly connected to the filter base 23 by bolts, and the connecting plate 29 and the filter base 23 are... The mesh frame 27 is sealed with a sealing ring; multiple bamboo charcoal filter elements 30 are evenly arranged inside the mesh frame 27; two symmetrical water channels are formed inside the water filter base 23 through the U-shaped plate 26. When clean water passes through these two water channels, it enters the interior of the mesh frame 27 and is continuously diverted and merged through the holes and straight grooves of the bamboo charcoal filter elements 30. This allows the clean water to fully contact the bamboo charcoal filter elements 30 during the flow, enabling the bamboo charcoal filter elements 30 to fully adsorb impurities in the clean water, thereby effectively improving the cleanliness of the clean water.

[0045] like Figures 8 to 11 As shown, the bamboo charcoal filter element 30 is square, and it slides in fit with the inner wall of the mesh frame 27. The bamboo charcoal filter element 30 has multiple holes evenly distributed along the axial direction of the mesh frame 27, and multiple straight grooves evenly distributed on the side of the bamboo charcoal filter element 30. The holes and straight grooves on the bamboo charcoal filter element 30 are arranged perpendicularly. By setting the bamboo charcoal filter element 30 into a porous structure with multiple straight grooves, the contact area between water and the bamboo charcoal filter element 30 is effectively increased, thereby improving the adsorption efficiency of the bamboo charcoal filter element 30.

[0046] like Figures 10 to 11 As shown, multiple partitions 31 are uniformly fixed to the side of the bamboo charcoal filter element 30 near the through groove 28; an elastic mesh plug 32 is slidably installed on the inner ring of the opening of the mesh frame 27; the partitions 31 separate adjacent bamboo charcoal filter elements 30, reducing the probability of bamboo charcoal filter elements 30 sticking together, and improving the flowability of clean water; the elastic mesh plug 32 fixes the bamboo charcoal filter element 30 inside the mesh frame 27, reducing the probability of the bamboo charcoal filter element 30 detaching from the inside of the mesh frame 27.

[0047] like Figure 1 and Figure 9As shown, a hinge 33 is fixedly connected to the middle of the top cover of the water filter base 23; an angle sensor 34 is fixedly connected to the end of the top cover of the water filter base 23 away from the threaded interface 25; a hydraulic rod 35 is hinged between the top side of the hinge 33 and the top cover of the water filter base 23; the angle sensor 34 is used to determine the degree of inclination of the water spray base 1, and in conjunction with the degree of inclination of the floor scrubber, to determine whether the floor scrubber is in a flat or inclined state, thereby providing a basis for the opening and sealing of the water spray base 1; at the same time, the angle of the water spray base 1 is adjusted in conjunction with the hydraulic rod 35, which not only reduces the probability of side leakage of the water spray base 1, but also facilitates the adjustment of the water outlet angle of the water spray base 1.

[0048] like Figure 2 and Figure 3 As shown, the flow channel 2 is divided into four cavities, and the four cavities are arranged in pairs; the two groups of cavities are symmetrically distributed along the middle of the water spray base 1 to both ends; the water outlet 3 is set at both ends of each cavity; the water outlet 3 is evenly distributed through the flow channel 2, and at the same time, the multiple water outlet 3 are in parallel inside the flow channel 2, so that the water outlet gap of the water outlet 3 is minimized, and the uniformity of water output from the water spray base 1 is improved.

[0049] like Figure 12 As shown, a floor scrubber employs the aforementioned anti-leakage integrated nozzle. The scrubber includes a body 36; a brush disc 37 is provided on the bottom surface of the body 36; the anti-leakage integrated nozzle is mounted on the brush disc 37 and provides clean water to the brush disc 37; a squeegee 38 is provided on the bottom surface of the rear of the body 36; during operation, the floor scrubber sprays clean water through the anti-leakage integrated nozzle, working in conjunction with the brush disc 37 to scrub the floor, while residual wastewater on the floor is collected by the squeegee 38; and when the floor scrubber is tilted, the anti-leakage integrated nozzle effectively prevents leakage.

[0050] Working principle: The water tank of the floor scrubber is connected to the threaded interface 25 through a pipe, which introduces clean water into the interior of the filter base 23. The U-shaped plate 26 forms two symmetrical water channels inside the filter base 23. When the clean water passes through these two water channels, it enters the interior of the mesh frame 27 and is continuously divided and merged through the holes and straight grooves of the bamboo charcoal filter element 30. This allows the clean water to fully contact the bamboo charcoal filter element 30 during the flow process, enabling the bamboo charcoal filter element 30 to fully adsorb impurities in the clean water. The clean water enters the interior of the spray base 1 through the through hole 24. The flow channel 2 evenly distributes the water outlets 3. At the same time, the multiple water outlets 3 are in parallel inside the flow channel 2, which minimizes the gap between the water outlets 3 and improves the uniformity of the water output from the spray base 1.

[0051] When the water spray seat 1 is in a horizontal state, the water flow is evenly distributed along the flow channel 2 to the water outlet 3, and then sprayed out from the water outlet 3; at this time, the elastic force of the springs 11 on both sides pushes the sliding sleeve 9 to slide along the guide rod 7 to the middle of the cavity 4, so that the counterweight seat 8 and the pusher 10 are located in the middle of the cavity 4, so that the pusher 10 is separated from the elastic tube 6, ensuring the unobstructed flow of the elastic tube 6;

[0052] When the spray base 1 tilts, the counterweight base 8, under the action of gravity, drives the sliding sleeve 9 to slide along the guide rod 7 towards the lower end of the spray base 1, causing the pusher 10 at the lower end of the counterweight base 8 to slide into the interior of the connecting groove 5. The pusher 10 pushes the middle part of the elastic tube 6, causing the middle part of the elastic tube 6 to bend and compress, squeezing and sticking the outer walls on both sides of the elastic tube 6 together, blocking the elastic tube 6, thereby preventing the water remaining inside the flow channel 2 from flowing out from the lower water outlet 3, and improving the dryness of the ground around the floor scrubber.

[0053] When the floor scrubber cleans a sloping surface, the spray base 1 is tilted and water needs to be discharged from the spray base 1. At this time, the waterproof motor 22 located at the lower end of the spray base 1 starts, drives the lead screw 21 to rotate, drives the bottom slider 18 to slide along the bottom guide rail 17, clamps and fixes the U-shaped magnet 20 through two L-shaped clamps 19, drives the U-shaped magnet 20 to move horizontally, so that one end of the U-shaped magnet 20 aligns with the adjacent square magnet 13, and the one end of the U-shaped magnet 20 repels the adjacent square magnet 13, pushing the lower end counterweight 8 to slide back to its original position, driving the pusher 10 to separate from the elastic tube 6, ensuring the unobstructed flow of the elastic tube 6, and ensuring the stability of the floor scrubber when working on a sloping surface.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
